True or Rewrite the in parentheses part to make it true.
11.The speed of a rotating object changes only if (torque) is applied to it.

12.The quantity of angular motion that is used with rotating objects is called (linear) momentum.

13.When a (torque) acts on an object, its angular momentum changes.

16.The torque on the planets orbiting the sun is zero because the gravitational force is directed toward the sun and, therefore, is not (perpendicular) to its velocity.

19.When a machine alters mechanical energy, the product of the force and distance is (zero).

I know how to solve other log equations, such as logx=3, but this problem has a smaller number between the log and x. I don't know how to type it in a calculator or on the computer so I hope I'm explaining this right. It looks similar to log^2(3)=x but the 2 is at the bottom of the log so it's not squaring it. I think the proper terminology is "log base of 2" but I could be wrong.

Anyway, the problem I need help solving is log(little 2)(1/16) = X. I don't really need the answer, just an explaination of how to solve this type of problem. Sorry if this is confusing and doesn't make any sense!

From about 5 yrs, it was late at night and i was talking to a friend on the phone when i notice a light flashing so quickly infront of my room. So, i think it was the electricity. I turn off the main switch and i come back to my room. The flashing light passes again! i saw it for about 4 times flashing and passing infront of my door room. Frankly, I was in panic and started crying. Anyone has any idea about what this might be?

Thank U so Much!

how would i work this problem...the answer is (4, -3, 1), but i have to show my work...

here's the equations:

5x + 7y = -1
-2y + 3z = 9
7x - z = 27

thanks for your help...i really appreciate it.

In mountainous regions, road builders construct runaway truck ramps near the bottoms of long hills. These ramps allow a truck with failed (not working) brakes to leave the main road and coast uphill to a stop on sand or gravel-filled paths. Explain why the sand or gravel helps stop the truck. (Hint: Think about running on a very sandy beach.)
